Abstract

An injection molding mechanism and method of its use for the formation in a single sequence of operations of weld-line free cylindrical container body portions having a central opening at one end. The central opening is formed by the removal of the central top sprue portion of the container body. The container body produced by this mechanism can be used as a pressurizable dispensing container.
